sg_safte - access SCSI Accessed Fault-Tolerant Enclosure (SAF-TE) device
sg_safte [--config] [--devstatus] [--encstatus] [--flags] [--help] [--hex] [--insertions] [--raw] [--usage] [--verbose] [--version] DEVICE
Fetches enclosure status (via a SCSI READ BUFFER command). The DEVICE should be a SAF-TE device which may be a storage array controller (INQUIRY peripheral device type 0xc) or a generic processor device (INQUIRY peripheral device type 0x3). If no options are given (only the DEVICE argument) then the overall enclosure status as reported by the option --config ®is reported.
Arguments to long options are mandatory for short options as well. The options are arranged in alphabetical order based on the long option name. -c, --config will issues a Read Enclosure Configuration ®(READ BUFFER ID 0) cdb to the device, which returns a list of the enclosure hardware resources. -d, --devstatus will issue a Read Device Slot Status ®(READ BUFFER ID 4) cdb to the device, which returns information about the current state of each drive or slot. -s, --encstatus will issue a Read Enclosure Status ®(READ BUFFER ID 1) cdb to the device, which returns the operational state of the components. -f, --flags will issue a Read Global Flags ®(READ BUFFER ID 5) cdb to the device, which read the most recent state of the global flags of the RAID processor device. -h, --help output the usage message then exit. -H, --hex output the response to a READ BUFFER command in ASCII hex to stdout. If used once, output the response to the first READ BUFFER command (i.e. with buffer_id=0). This should be the enclosure configuration. If used twice (or more often), the response to subsequent READ BUFFER commands is output. -i, --insertions will issue a Read Device Insertions ®(READ BUFFER ID 3) cdb to the device, which returns information about the number of times devices have been inserted whilst the RAID system was powered on. -r, --raw output the response to a READ BUFFER command in binary to stdout. If used once, output the response to the first READ BUFFER command (i.e. with buffer_id=0). This should be the enclosure configuration. If used twice (or more often), the response to subsequent READ BUFFER commands is output. -u, --usage will issue a Read Usage Statistics ®(READ BUFFER ID 2) cdb to the device, which returns the information on total usage time and number of power-on cycles of the RAID device. -v, --verbose increase the level of verbosity, (i.e. debug output). -V, --version print the version string and then exit.
This implementation is based on the intermediate review document dated 19970414 and named "SR041497.pdf". So it is quite old. Intel and nStor are the authors. Intel have a zip archive containing this and related documents in the "SAF-TE: SCSI Accessed Fault Tolerant Enclosures Interface Specification" section of this page: http://www.intel.com/content/www/us/en/servers/ipmi/ipmi-technical-resources.html Similar functionality is provided by SPC-4 SCSI Enclosure Services (SES) devices (Peripheral device type 0xd), which can be queried with the sg_ses utility.
To view the configuration: sg_safte /dev/sg1 To view the device slot status: sg_safte --devstatus /dev/sg1
The exit status of sg_safte is 0 when it is successful. Otherwise see the sg3_utils(8) man page.
